Angiopoietin-like proteins (ANGPTLs) represent a family of eight secreted glycoproteins that show structural homology to angiopoietins and carry distinct physiological functions, including putative roles in lipid metabolism, expansion of stem cells, inflammation, tissue remodeling and angiogenesis. In recent years, three ANGPTLs, ANGPTL3, ANGPTL4 and ANGP-TL8, have been shown to play a role in lipid metabolism and in the regulation of plasma lipid levels. ANGPTL4 and ANGPTL8 form a complex when refolded together and that ANGPTL4 in that complex loses its ability to inactivate LPL. Angiopoietin-like protein 4 (ANGPTL4) is a secreted 50 kD protein that modulates the disposition of circulating triglycerides (TG) by inhibiting lipoprotein lipase (LPL). ANGPTL4 is a positive acute phase protein and its increase could contribute to the hypertriglyce-ridemia that characteristically occurs during the acute phase response by inhibiting LPL activity. |
